NUT-LOCK.

dean and State of Missouri, have invented certain new and useful Improvements in Nut-Locks, of which'the following is a specification, reference being had to the accompanying drawings.

This invention relates to new and useful improvements in nut locks and more Vparticularly to a lock adapted for application to a rail joint and the like', the object of the invention being to provide a nut lock of the above character which -willlock a plurality of nuts against rotation thus materially assist-ing in securely holding the fish plates upon a rail joint in their operative position.Y

Another objectof the invention vis to provide a nut lock of the above character which will possess advantages in points of efficiency and durability, is inexpensive of manufacture and at the same time is simple inconstruction and operation.

With the above and other objects in view, this invention consists in the novel features of construction and the combination and arrangement of parts to be hereinafter more fully described, pointed out in the claim and shown inthe accompanying drawings, in which- Figure 1 is a side elevation of a nut locking device constructed in accordance with my invention; Fig. 2 is a horizontal scctional view; Fig. 3 is a detail perspective view of one end 'of the bearing plate; Fig. 4 4is a detail perspective view of one end of the locking plate; and F ig. 5 is a detail enlarged sectional view illustrating the rela:

tive position of the reinforcing members with respectl to the nuts.

Referring more particularly to the drawings, 1 and 2 indicate the meeting ends of two rails which are held against lateral movement by the rail chair: 3, the vertical spaced uprights of saidchair being securely fastened to the rails 1 and 2 by means of the bolts 4:, said bolts having nuts 5 upon one end thereof to hold the same in their oper- .ative position. 'These nuts 5 are securely held against rotary movement through the medium of a plate 6 which is mounted upon the bolts 4 and disposed between'the nuts and the side port-ions of the rail chair The plate 6 is provided at each end thereof with a loop 7, said collars projecting through specification of Letters Patent.

the openings S formed in the locking plate 9. -Securing pins 10 are inserted within the loops 7 after the locking plate has been placed in position to securely hold said lock-` ing'plate against longitudinal movement.

The locking plate t) is provided with a plurality of openings 11 which are adapted to receive the nuts 5 threaded upon the outer ends of the bolts 4 to hold the same against rotary movement.. The vmaterial which is cut from the openings 11 is bent back in opposite directions so" as to reinforce the edges `of the openings and adapted to engage the sides of the nuts -5 to securely hold them against' rotary movement.. It will be apparent that/by forming the openings 1l, the

side edges of the same, as shown at 12 and posite sides of the nut. From this itwillbe seen that in securely locking the nuts 5 against rotation, the plate- 6 is placed upon the bolts and locked in posit-ionby threading the nut-s 5 upon the outer ends of the bolts. The locking plate 9 is then engaged over the n uts, the loops 7 project through the openings 8 in saidplate and having the pins 10 inserted therethrough to securely hold the plate against lateral movement, it being understood that the nuts 5 will hold the plate against longitudinal movement.

From this it will be apparent v that I have' provided a simple and durablemut locking device which is particularly adapted for locking nuts upon rail joints and the like and which at the same time will securely lock aplurality of nuts against rotation., It will also be apparent that my device is cxtremely" simple in construction and can be manufactured at a. comparatively low cost.

While I have shownand described the preferred form of my invention, it will be obvious that various changes in the details of construction and in the proportions may fish plate, loops formed upon eaehvend of and engage the sides of the nuts vto prevent 10 seid plate, a. looking plate having openings rotation of the same.
